SmartClient
SmartClient is set of mobile and cross-browser HTML5 UI components combined with a Java-based Ajax framework, created by Isomorphic Software to build business web applications. First released in 2001, SmartClient was integrated into products from the software vendors including Informatica and Wily/CA. Since November 2007, SmartClient was available free under an open source LGPL licence, and some of its code may be available on GitHub. It is also available under a commercial licence.
SmartClient mentions among its competitors Vaadin, Apache Flex and Sencha's Ext JS, and is similar to full-stack business web application development frameworks like Wakanda.
